kernels as also ELF ones. Also cleaned up the code a bit and removed a
bunch of errors in the ELF loading code... no wonder it didn't work ! ... I
tried to squeeze about 8000 bytes in one 4096 byte page resulting in a
corrupted bss.
bootable GENERAL kernel for the 3 machines.
This is done by integrating the ARM7500 in a better way. In various places
the IOMD ID is checked and action is taken at runtime compared to
compiletime.
The small piece of assembler that is changed now uses the flag
`arm7500_ioc_found' that is set up by iomd.c at startup. When this chip
isnt found at startup it will skip reading the ARM7500 extended IRQ
registers and wont clear them either.
The next step will be getting the mode-definition files to the bootloader.
Currently they are compiled in.
to do notably the mouse, some issues about 4 bpp modes and most of all Xwscons !
This code will still allow usage of the old vidcconsole complete with X etc.
Note that the wscons code can now only be booted with the new bootloader but
kernels compiled with vidcconsole can still be booted the old way.
Initially I gave it the type `int *iomd_base' but some macro's defined in
iomdreg.h calculated with the value asuming it to be an int ... thus all the
registers offsets were multiplied by four and that can only mean trouble !
The kernel boots again ever happily. Sorry for the inconvenience... it was
a good bug hunt though!
When the IOMD isnt mapped and all is mapped 1:1 a read gives garbage and thus
the obscure feature that slows down printing (or halts it!) when the mouse
button is pressed during output to the vidcconsole gets allways activated.
Included a simple flag that signals if the IOMD is mapped; the delay routine
won't check the mouse if this flag is still clear.
<vm/pglist.h> -> <uvm/uvm_pglist.h>
<vm/vm_inherit.h> -> <uvm/uvm_inherit.h>
<vm/vm_kern.h> -> into <uvm/uvm_extern.h>
<vm/vm_object.h> -> nothing
<vm/vm_pager.h> -> into <uvm/uvm_pager.h>
also includes a bunch of <vm/vm_page.h> include removals (due to redudancy
with <vm/vm.h>), and a scattering of other similar headers.
Further cleanup and simply the allocation and mapping of the kernel
pagetables and static data pages.
Removed the page directory page table as it is no longer necessary.
Changed the allocation of the proc0 L1 page table and L2 page table
that maps the page tables to map these pages into kernel virtual
address space.
Updated for pv_addr_t argument changes to pmap_bootstrap().
Simplified serveral parts of the initarm() to make the code clearer and
modified parts of initarm() as part of an on-going effort to abstract
out part of initarm() on various machines.
This is necessary as the memory addresses being used for the cache clean
(if the CPU is a SA110) may have been remapped by the setttb() call and
thus the cache could loose sync with memory.
howto to dictate what operations to perform.
Removed support for calling the deprecated kshell stuff.
Cleaned up a few bits of dead code and renamed rpc_sa110_kickstart() to
rpc_sa110_cc_setup().
